(EMCIE) Backup & Recovery – Data Domain requirement?

Hi,

My name is Jose Miguel, The company where I work is partner of EMC.

I need to certficate in DATADOMAIN implementation. I have a doubt about the exams requirement.

To be a EMCIE of DATADOMIAN I need to pass E10-001 and E22-290 exams.

Actually I have already passed the E20-001 exam.  My questions is if I have to take both exams (E10-001 and E22-290) or only need to take E22-290 exams to became EMCIE DATADOMAIN?.

Thank you.

JM
